Perpetual fusion

:surprised In normal hydrogen bomb tritium and deuterium atoms fuse and lithium-6 is used as a regenerator of tritium.I have got a new alternative in which the regenerator is produced in the reaction itself .Here is it-

T + P => 2n + 2p {eq .taken in multiple of two}

4p => He-4 + e+(positron) + v {Energy released}

e+(positron) + 2n + He-3 => T + 2p

p + e+(positron) + 2n => He-3

Thus in whole process almost everything is recovered and until it gradually changes into energy.

But if we carry the reaction in (positron atmosphere )...imaginary.
THen,we have only two reactants to combine, I thought that main problem in this unrealistic rection is to combine triton and proton to form isolated neutrons and protons!
Better if u consider it as a totally new rubbish idea!

The positron would more likely annhilate with an electron. He-3 would readily absorb thermal neutrons, but in the fission/fusion reaction, the neutrons are prompt and fast (> 1 MeV). I don't see 2n combining with He-3, and even if one did to form He-4, He-4 has a very, very low absorption cross-section for neutrons - it is one of the most stable nuclei.

If the source of positrons is - 4p => He-4 + e+(positron) + v {Energy released} - this is not going to happen in a thermonuclear explosion. There is a reason the DT and LiD reactions were selected - among them, the fact the energy release of p+p-> d+e+ is only 1.4 MeV, and another - the cross-section of pp is very low, i.e. has low probablity of occuring. http://csep10.phys.utk.edu/astr162/lect/energy/ppchain.html
